Former Vice President Joe Biden’s performance at the CNN climate change town hall was roundly panned as offering vague, evasive answers on climate policy and an upcoming fundraiser with a fossil fuel executive — although many viewers were apparently just distracted and grossed out by his left eye, which inexplicably filled with blood during the event.

Numerous online critics called out Biden for noncommittal responses and thought that he struggled to offer coherent replies. That last criticism centered on a question from an audience member who took direct aim at the 2020 presidential candidate’s pledge to refuse money from the fossil fuel industry, by confronting Biden about the fundraiser the candidate has scheduled for the very next night at the home of a natural gas executive.

.@JoeBiden‘s answer on fracking was a rambling incoherent mess. Honestly, the more he talks, the more it is clear he is declining cognitively rapidly. It’s irresponsible of the Democratic Party and media to pretend these are “gaffes.” He is not well #ClimateTownHall

A question now from a fellow Pennsylvanian about the threat of fracked natural gas and what his policies will be. @JoeBiden‘s response seems pretty diffuse and noncommittal. Says he’ll stop new drilling but not call for a ban, and impose safety standards.#CNNClimateTownHall

An average Joe Biden sentence is like, “And look folks, this is America. And I don’t just mean this is America, I mean this is and you see what I mean. And on the flipside, it’s like my gruncle my grunc my uncle said to me. He said look Joe. Anyway. I’m talking too long.”
